I only wish all stock investements would be profitable and that goes for one's held for short periods as well as those tightly held for way too long. Personally I find it next to impossible to sell at high or buy at the low but close can be OK and selling Noront at $7 and buying back at between $5 and $6 wasn't impossible. If one believes Noront has the 'right stuff' watching further deteriation below $4 for a short period wasn't quite as painful as having held on for dear life expecting that run to continue up to $10.
With Noront being watch carefully by Forum members and a good understanding of what news means to the bottom line it is, I feel, possible to get some grip on when the price runs up too high to be sustainable in the short term. Of course the market does seemingly crazy things and yes you can misjudge timing/price but if you're not greedy and see an opportunity there is nothing wrong in exercising your judgement.
